OSTRA PRESENTATION

OSTRA is a 3-point mounted mechanical seed drill that is easy to use and suitable for all tractor powers. Fitted with a spur-type distributor, it offers good precision and can be used to sow a wide range of seed sizes. The V-shape of the hopper (and all its equipment) means that even the smallest seeds can be sown right down to the last grain. OSTRA uses discs or coulters as sowing units, depending on the type of terrain.

OSTRA RETAILING OSTRA features a 3-cam gearbox for even distribution at all working speeds. The cams are protected by an oil bath with level indicator. Distribution is easily adjusted by means of a crank and a graduated selector, which can be adjusted using an adjustment table. OSTRA uses a spur feeder for precise metering, and can sow both small and very large seeds (thanks to the two sizes of spur). Switching from one size of seed to another is quick and easy. Small and large dewclaws The OSTRA hopper is V-shaped to optimise the bottom of the hopper. This shape, together with an...

OSTRA THE SEEDING ELEMENTS OSTRA can be fitted with staggered double discs. Their smooth, sharp shape breaks up clods and ensures good soil penetration. The offset discs ensure that debris is removed. Double offset discs These simple discs, fitted with scrapers, can be used on all types of soil, forming a furrow to allow the ploughshare to bury the seed. Single discs

These sowing units combine a metal disc, a rubber pad and a ploughshare, forming a furrow with the disc to allow the ploughshare to sow the seeds. Due to the rubber element, the furrow does not close and the disc is not slowed down or dirtied by the soil. In addition, the disc can be used to set the seeding depth. Discs with rubber rollers At the rear of each type of disc, press wheels ensure uniform depth and compact the soil. They are adjusted using pins. Pressure roller adjustment ploughshares, which are particularly effective in difficult, damp soils. They are fitted with a protective...

The pressure exerted on the sowing elements can be adjusted using a crank. It operates by means of a spring that tensions and relaxes, varying the level of pressure. Pressure adjustment TESTING AND DRAINING TRAYS For optimum metering, OSTRA includes test and emptying trays. These are built into the seed drill and are easy to transport. So they can be used anywhere for a flow or emptying test. Test and drain trays LOADING BOARD Due to its easy-access loading bridge, OSTRA enables the hopper to be filled and inspected in complete safety. Loading bridge

HARROW The OSTRA seed drill is fitted with a tine harrow. This prevents clogging and ensures perfect levelling after sowing. Narrow-tine harrow HYDRAULIC TRACERS OSTRA uses track markers to ensure even sowing. They operate hydraulically, making them easy to fold in and out, and feature a bolt-operated safety device, useful in the event of obstacles. 2 spare bolts are fitted directly to the machine, so you can change them quickly if necessary.

OSTRA Options Several options can be added to the seed drill: A 2x2 electric closing box with pre-emergence tramlining, which manages speed, area and distance covered. It includes a lift sensor on the 3rd point. In addition to the electric box, it is possible to add a 2x2 row electric row lock. This operates automatically and is counted down each time the seed drill is lifted. This 2x2 closure means that the seed can be sown depending on when the sprayer is subsequently used.

Two pairs of height-adjustable, spring-loaded erasers. Electric pre-emergence tracers, to leave a wake for spraying just after sowing (before the crop emerges).
